Journal Article The Problem of Fit between Ecosystems and Institutions: Ten Years Later(2007) Folke, Carl; Pritchard, Lowell; Berkes, Fikret; Colding, Johan; Svedin, Uno"The problem of fit is about the interplay between the human and ecosystem dimensions in social-ecological systems that are not just linked but truly integrated. This interplay takes place across temporal and spatial scales and institutional and organizational levels in systems that are increasingly being interpreted as complex adaptive systems. In 1997, we were invited to produce one of three background papers related to a, at that time, new initiative called Institutional Dimensions of Global Environmental Change (IDEG), a research activity of the International Human Dimensions Program of Global Environmental Change (IHDP). The paper, which exists as a discussion paper of the IHDP, has generated considerable interest. Here we publish the original paper 10 years later with an extended introduction and with reflections on some of the issues raised in the original paper concerning problems of fit."Conference Paper Framework for the Study of Indigenous Knowledge: Linking Social and Ecological Systems(1995) Berkes, Fikret; Folke, Carl"A considerable amount of evidence has accumulated to indicate that ecologically sensible indigenous practices have indeed existed in diverse ecosystems. Based on these findings, there is potential for improvement of resource management in environments such as northern coastal ecosystems, arid and semi-arid land ecosystems, mountain ecosystems, tropical forest ecosystems, subarctic ecosystems and island ecosystems. As compared to the rather narrow set of prescriptions of Western scientific resource management systems, some of which may inadvertently act to reduce ecosystem resilience, indigenous management is often associated with a diversity of property rights regimes and common-property institutions and locally-adapted practices, and it may operate under systems of knowledge substantially different from Western knowledge systems. "The framework we propose distinguishes seven sets of variables which can be used to describe social and ecological system characteristics and linkages in any indigenous resource use case study: (1) ecosystem, (2) resource users and technology, (3) local knowledge, (4) property rights, (5) institutions, (6) pattern of interactions, and (7) outcomes. Our framework borrows from that of Oakerson for the analysis of common-property management, and that of Ostrom for institutional analysis. "The key concept in our framework is resilience, to emphasize the importance of conditions in which disturbances (perturbations) can flip a system from one equilibrium state to another. We use Holling's definition of resilience, the magnitude of disturbance that can be absorbed before a system changes its structure by changing the variables and processes that control behavior. We hypothesize that: (1) maintaining resilience is important for both resources and social institutions, and therefore the well-being of social and ecological systems is closely linked; (2) successful traditional knowledge systems will allow perturbations to enter an ecosystem on a scale which does not threaten its structure and functional performance, and the services it provides; and (3) there will be evidence of co-evolution in such traditional systems, making the local community and their institutions "in tune" over time with the natural processes of the particular ecosystem."
